Love is hard work!

"Life is to be fortified by many friendships.
To love and to be loved
is the greatest happiness of existence."          - Aesop

Note that this quote does not simply state "To be loved is the greatest happiness of existence."  Merely being loved without feeling loving in return does not bring true happiness.   It takes effort to love someone.
Whether it's a parent, a child, a grandparent, a soul mate or a friend, loving involves effort.  Remembering birthdays,  truly listening to them both in good times and bad and being there for them when they need someone.  Sometimes it requires even putting their needs ahead of your own.    Today, truly give an act of love to someone close to you.  It will add happiness to your day as well as theirs.
